Description

Technical Field

[0001] The utility model relates to the technical field of coding devices, in particular to a coding device for a packaging bag printing machine. Background Art

[0002] Coding refers specifically to the process of printing information codes by a printer, such as printing production date, barcode, QR code and serial code on product packaging, which can be called coding. A printer is a machine used to print characters (such as production date, shelf life, batch number, etc.), icons, specifications, barcodes and anti-counterfeiting logos on the surface of products. Its advantages are that it does not contact the product, the printing content is flexible and changeable, the character size can be adjusted, and it can be connected to a computer for complex database printing.

[0003] Currently, there is a food packaging bag printing machine coding device with application number 202321120211.X, which includes a frame, a conveyor belt is movably installed on the inner side of the frame, and fixed frames are fixedly installed on the left and right sides of the top of the frame. A flattening roller located above the conveyor belt is provided between the two fixed frames, and a mounting shaft is fixedly installed on the left and right sides of the flattening roller. The utility model can contact the outer side of the flattening roller through the top of the packaging bag. At this time, the packaging bag with a certain thickness can apply an upward force to the flattening roller. At this time, the movable block is displaced upward relative to the fixed frame under the action of the card slot. At this time, the movable rod moves up and compresses the limit spring until the flattening roller moves upward. At this time, the outer side of the flattening roller can always keep in contact with the packaging bag, and apply friction to the top of the packaging bag to achieve the flattening operation of the packaging bag, ensure the flatness of the packaging bag surface, and reduce the influence of wrinkles on the packaging bag surface on the coding.

[0004] After the improvement, when the device is used for coding on packaging bags, the position is not standardized and the angle is skewed, which affects the quality of the product. At the same time, after the coding is completed, the vibration touch causes the coding pattern to be blurred. For this reason, we propose a coding device for packaging bag printing machine.
